Experimental Study of Natural and Artificial Waste as a Partial Replacement of Coarse Aggregate in Concrete

The properties of concrete using coconut shell and crushed glass as a partial replacement of coarse aggregate were investigated in an experimental study. Compressive strength, split tensile strength and flexural strength were measured and compared it with conventional concrete properties as recommended by the standards. Two concrete grades such as M20 and M30 were used. Coarse aggregate was replaced by coconut shell and crushed glass in four different percentages namely 0%, 10%, 20%, 30% and 40%. In this study 36 cubes, 36 cylinder and 36 beams were casted with constant water cement ratio of 0.45. super plasticizers conplast SP 430 DIS were used to reduce the water content in the concrete. As per the result it is concluded that coconut shell and crushed glass offers as a potential building material and simultaneously solving the environmental problem of reduction in natural and artificial waste.
